2.5 Correcting a Probe Phase
Before using a probe to make measurements, be sure to correct the probe phase.
CAUTION
Do not apply external voltage to the signal output terminal for probe compensation adjustment.
This may cause damage to the internal circuitry.

ATTENTION
Ne pas appliquer de tension externe sur la borne de sortie de signal afin d'ajuster la
compensation de sonde. Cela pourrait endommager le circuit interne.
Procedure
1.
Turn on the power switch.
2.
Connect the probe to the input terminal to which the signal is to be applied.
3.
Connect the tip of the probe to the signal output terminal for probe compensation adjustment on
the front panel of the instrument and connect the ground wire to the functional ground terminal.
4.
Follow the instructions in section 3.6, “Performing Auto Setup,” to perform auto setup on the
probe.
5.
Insert a flat-head screwdriver into the phase adjustment hole and turn the variable capacitor to
make the displayed waveform a correct rectangular wave.
